OKX to change the funding rate formula for perpetual futures
To provide you with a better experience, OKX will change the funding rate formula for perpetual futures in live trading in 3 batches, April 10, 2025, 12:01 am UTC, April 17, 2025, 12:01 am UTC and April 24, 2025, 12:01 am UTC.
For perpetual futures with an 8-hour settlement interval: The new funding rate formula will take effect at 12:01 am UTC. As a result, the funding fee settled at 8:00 am UTC will be based on the funding rate calculated from the new formula.
For perpetual futures with a 4-hour settlement interval: The new funding rate formula will take effect at 12:01 am UTC. As a result, the funding fee settled at 4:00 am UTC will be based on the funding rate calculated from the new formula.
For perpetual futures with a 2-hour settlement interval: The new funding rate formula will take effect at 12:01 am UTC. As a result, the funding fee settled at 2:00 am UTC will be based on the funding rate calculated from the new formula.
Note: All perpetual futures in demo trading will be using the new funding rate calculation by March 19, 2025, 8:01 AM UTC.
Details about the formula changes can be found below.
Original funding rate formula | New funding rate formula | |
Funding rate formula | Funding rate = Clamp [MA (Premium index – Interest rate), Funding rate cap, Funding rate floor] | Funding rate = Clamp [Average premium index + Clamp (Interest rate – Average premium index, 0.05%, -0.05%), Funding rate cap, Funding rate floor] Note: The average premium index is calculated using an exponential moving average. For more details, refer to our product documentation. |
Interest rate | 0 | 0.03% / (24 / Settlement interval) Taking a BTCUSDT perpetual futures contract as an example, funding fees are charged or paid out every 8 hours, so the interest rate = 0.03% / 3 = 0.01%. Note: Some perpetual futures will have no interest rate. This only applies to USDCUSDT perpetual futures at the moment. |
Premium index | Premium index = [(Best bid + Best ask) / 2 - Index price] / Index price | Premium index = [Max (0, Impact bid price – Index price) – Max(0, Index price – Impact ask price)] / Index Price Note: Impact bid and ask prices are calculated using impact value. For more details, refer to our product documentation. |
